He knew he was approaching the bottom because he could hear Sophie, shouting through into the tunnel to Roger. Her words were blurred by echo, but he could tell she was standing quite close to him. Then he did turn and saw he was only six feet from the ground. He slid it on his backside and landed beside her, one foot slipping on a slimy rock into a pool. There was no direct sunlight there; a strong smell of rotting seaweed, organic and salty. It was somehow prehistoric. He tried not to think about the return to the real world.
‘What have you found?’
‘We didn’t like to touch it. This way.’ She led him into the mouth of the tunnel.
The floor was uneven – shingle, solid rock which formed crevasses and pools, and small smooth boulders which must have been washed in from the beach. Too late he remembered a directive he’d received a couple of months ago about risk assessment. He wondered what Health and Safety would make of this. Roger and Sophie weren’t even employees.
At this point the tunnel looked like a cave. It must curve further in and the gap leading to the open water must be very narrow, because no natural light showed from the other end. Roger had put on his torch and was waiting for them, haloed in a yellow glow. He was sitting on an outcrop of rock which jutted from the channel wall, eating a bar of chocolate.
‘Sorry,’ Sophie said. ‘Jimmy was a tad slow.’
‘Have you found Booth’s phone then?’ Perez thought they were playing a sort of practical joke on him. They knew he was uncomfortable with heights and had dragged him down here under false pretences. They’d pull out some ridiculous object that had been washed in – a pair of false teeth, an old boot – and expect him to find it amusing.
‘No,’ Roger said. ‘But we found this.’
He shone his torch into a pile of debris which had been lifted on to a shelf in the rock. There were scraps of fishing net, shell and seaweed, two of the plastic rings which hold four-packs of beer and, creamy and smooth, a piece of bone.
‘Very funny,’ Perez said. A sheep had become trapped down here, starved to death. It wouldn’t take long for the flesh to rot and be eaten away by fish and other creatures. When it was exposed to the air the bonxies and the rats would have it. The tide would have lifted the small piece of bone on to the ledge.
‘What do you think it is?’
‘Sheep? Dog maybe?’
‘Look closer,’ Roger said. ‘I think you’re wrong. If I’m not mistaken it’s a human thigh bone.’
‘Roger works as a physio,’ Sophie said. ‘He knows about human anatomy.’
Perez could tell she was enjoying herself. It was that excitement around unexplained death again.
‘It must have been pushed up to the ledge on a really big tide.’ Roger played the torch along the tunnel wall, half a metre below the ledge. ‘You can see this is the normal high-water mark.’
‘So it could have been flushed in from the open sea?’ Perez said. He wondered how many men had been lost in the seas around here over the years. The currents were so fierce that it wasn’t unusual for the bodies from wrecks never to be recovered. The bone was worn shiny and smooth. It had been here for ages.
‘It wouldn’t take very long for it to get like that,’ Roger said, seeming to read his thoughts. ‘I mean not decades. Not necessarily. Not down here. Think of the action of the sand and the shingle.’
‘When was the last really high tide? I mean, when do you think it was lifted on to the ledge?’ Perez found his thoughts moving very fast. It was as if he’d had a shot of caffeine.
‘This year,’ Sophie said quickly. ‘Spring equinox. Don’t you remember, those wonderful photos in the Shetland Times of the waves at Scalloway? It could have been here in the tunnel before that but washed on to the ledge then.’
‘I need to get right to the end of the tunnel.’ Perez had forgotten any question of risk assessment. ‘I need to know how big the entrance is on the seaward side.’
They walked in single file with Roger in the front, Perez in the middle and Sophie at the rear. The way into the tunnel from the Pit was wide enough for them to stretch out their arms, but it narrowed as they approached the shore. A slit of natural light appeared ahead of them, and there was a gust of salt fresh air from the sea. Now they were clambering over solid rock. Before they could reach the gap the tunnel had become so tight that they couldn’t move further forward. Sunshine shone through the strange vertical crack, picked out the colour in the rock at their feet in a sparkling strip.
‘A body couldn’t have been washed in there,’ Perez said. ‘Even with the force of the tide behind it. There’s no room.’ Sandy needn’t have worried about leaving Booth’s holdall down here. There was no way it would have been washed through the tiny gap.
‘Couldn’t the body have broken up at sea? A bone the size we found could just about have been sucked in.’
Still Perez’s thoughts were racing. ‘That’s possible. But if we find any more than that, it would be more than chance. Think of all the places along the coast where they could be washed up. And if we discover part of a corpse which is bigger than the piece we found, it couldn’t have come in this way.’ He looked at them. ‘Could it? The gap’s too narrow. If we come across more bones, or a bigger fragment of bone, it means the body was tipped down from the top of the Pit. Like Roddy Sinclair. It means another, older murder.’
Chapter Thirty-five
On Monday afternoon Fran went to visit Bella. She’d been thinking all weekend that she should go. She wasn’t sure what she could do to help, but the death of someone so young and beautiful needed marking. It demanded a certain ritual. She knew Bella would see things that way too. Fran thought she would be waiting in the Manse, queenly, expecting visits. That didn’t mean Bella would be feeling the loss any less – Roddy was as much a child to her as Cassie was to Fran – but she would want his going dramatized, turned into art, made splendid.
There was a small group of reporters at the entrance to the Manse. None of them looked local. They seemed content to sit in the sun and take photos of the Manse with their long lenses. A uniformed policeman stood there too, and he seemed to be enjoying the banter with the journalists. He let Fran through with a wave when she said she was there to see Bella. She thought she’d seen him before at one of Duncan’s parties. Those days seemed a long time ago.
Bella opened the door to her and as Fran had expected she was dressed to meet guests. Her clothes always tended towards the theatrical. Today she was wearing a long skirt, gathered and full, in a plum-coloured muslin, and a white embroidered cotton top. The effect was exotic – flamenco or gypsy. Fran despised herself for considering such trivial matters as dress, but Bella would want it to be noticed. Fran wondered if it would be tasteless to say how nice the artist looked and decided that it would be. Besides, she would know she looked good.
‘I wanted to come,’ she said. ‘I probably can’t do anything, and if you’d rather be alone, do say.’
